INFLUENCE OF HIGH REACTIVE META KAOLIN ON FLEXURAL STRENGTH OF CONCRETE

Abstract

The present study is directed to understand contribution of High reactive Meta kaolin on flexural strength of high strength concrete. Experimental investigation was carried out over water cement ratio varying from 0.32 to 0.40. OPC replaced by HRM raging from 5-15% by the weight. For all mixes compressive strength was determined at 28 days. It was observed that the optimum replacement percentage is not a constant one but it depends on water cement ratio of the mix. Test result reveals that w/c ratio 0.38 produces compressive strength nearly equals to target mean strength for all replacement levels. It also improves flexural strength of concrete for all replacement levels.
